I would like to ship support for the 'overscroll-behavior' CSS property (formerly called 'scroll-boundary-behavior') in Firefox 59.
Preference behind which the feature was developed: layout.css.overscroll-behavior.enabled "Intent to implement" thread: https://www.mail-archive.com/dev-platform@lists.mozilla.org/msg23947.html Tracking bug for shipping: https://bugzilla.mozilla.org/show_bug.cgi?id=1428879 Draft spec: https://wicg.github.io/overscroll-behavior/ There have not been any significant changes to the spec since the "Intent to implement" email, except for the change of name from 'scroll-boundary-behavior' to 'overscroll-behavior'. Support by other browser engines: Blink: Shipping in Chrome 63 [1] Edge: Public support [2] WebKit: No public signals Testing: The feature has a manual web-platform-test [3]. The Chromium folks are working on upstreaming an automated web-platform-test [4]. Example: #chatbox { /* Excess scrolling on the chatbox will not be handed off to its parent scrollable .*/ overscroll-behavior: contain; } See [5] for more examples.
